Description

General description

Iron(II,III) oxide is an earth-abundant magneticoxide that has a high specific surface area, and good dispersion. The presenceof Fe³⁺ and Fe²⁺ with equal numbers in the Fe₃O₄structure provides higher light absorption and as a result superiorelectrocatalytic activities and high performance in solar cells compared toother iron oxides.

Application

Iron(II,III) oxide can be used as:

• A starting material to synthesize Ca₂Fe₂O₅ (srebrodolskite) microspheres via a single-stage flame spheroidisation (FS) process.
• A catalyst for reverse water gas shift reactions(RWGS).
